MW BY Patented Nov. 7, 1950 POCKET ATOMIZER' Arthur Arbetman, Newark, N. J., assignor to Rodman Trading Corp., Little Neck, N. Y., a corporation of New York Application January 3, 1948, Serial N 0. 437

4 Claims.

This invention relates to atomizers for spraying perfume or the like, and more particularly to an improved construction for use in the Cosmetic Device shown in my copending application, Serial No. 766,068, filed August 4, 1947, of which the instant application is a continuationin-part.

The atomizer shown in my said copending application is arranged to be closed by an associated liquid cosmetic holder and to act as a closure for a lipstick applicator. As described in said application, the atomizer includes a liquid compartment formed by angularly intersecting passages drilled in the atomizer casing and closed at the lower end by a plug. An air passage and a pump chamber are drilled in the easing and connected by a cross-passage drilled laterally of the casing and likewise closed at its lateral end by a plug.

The present invention is directed to an improved construction eliminating the more complicated drilling and plugging operations used in the atomizer. In the present construction, four longitudinal passages are drilled in the casing in parallel relation. Three of these passages are substantially equal in diameter, while the fourth is of larger diameter. Two of the smaller di ameter passages act as a liquid container and are closed at their outer ends by a filler cap and a liquid nozzle, respectively. The third small diameter passage is an air chamber closed at its outer end by an air nozzle for directing air across the liquid nozzle to aspirate liquid therethrough. The fourth passage is a pumping chamber, acting as a cylinder for a plunger actuated piston to force air through the air chamber.

A novel feature of the invention is the manner of providing cross connections between the two passages of the liquid container and between the air chamber and the pump chamber. This is accomplished by milling or otherwise cutting shallow slots in the casing material separating the two liquid passages and in that separating the air and pump chambers. A plate is then secured to the lower end of the atomizer and provided with interior circular bosses fitting each of the drilled passages, with connecting bosses between the circular bosses and aligned with the slots. The heights of the connecting bosses are less than the depths of the slots, so that small area cross passages are left respectively connecting the two liquid passages together and the air chamber to the pump chamher.

An object of the invention is, therefore, to provide an improved atomizer construction. Another object is to provide an improved and simplified internal construction for an atomizer. These and other objects, advantages and novel features of the invention will be apparent from the following description and the accompanying drawing. In the drawings: Figs. 1 and 2 are respectively top plan and elevation views of the atomizer in the closed or inoperative position. 1

Figs. 3 and 4 are top plan and elevation views, respectively, of the atomizer in the operative po sition. I

Figs. 5, 6 and 7 are transverse sectional views on the lines 55, 6-6 and 'l'l, respectively of Fig. 1. I

Fig. 8 is a top plan plan view of a bottom closure plate for the atomizer.

Referring to the drawing, the atomizer, which is generally similar to 'thatshown in-- my said copending application, includes a casing or body lo'having a shoulder ll. As described in my copending application, the atomizer is closed by a liquid cosmetic applicator having a casing whose lower end fits over shoulder ll. Simi l'arly, a shell fits over casing [0 against shoulder I I and extends beyond casing ID to act as a closure for a lipstick applicator.- As the associated liquid cosmetic and lipstick applicators are-sub: stantially the same as in my copending application, they have been omitted from the drawing to simplify the same and because the present invention is directed to construction improvements in the atomizer.

Casing Ill has four passages 15, 20, and drilled longitudinallythereof, with passages I5, 20 and 25 being relatively small in diameter and passage 30 being relatively large in diameter. Passages l5 and 20 combine to form a liquid chamber, and are closed by a filter cap I6 and a liquid nozzle member 2|, respectively. The upper end ofpassage I5 is threaded, to receive cap l6, and ends in an enlarged recess I! in which a flange 18 on cap 16 seats to seal passage 15. An air inlet is formed by a slot 19 milled in recess l! and through threads l2.

Nozzle member 2| has an enlarged upperend 22 press-fitted in passage or bore 20* and terminating in a conical nozzle 23. A liquidtube 24 extends downwardly from section 22 into passage 20.

Passage or bore 25 forms an airchamber, whose upper end is closed by an air nozzle memher 26. Member 26 includes a reduced boss 21 press fitted in bore 25 and an enlarged nozzle portion 28. An air nozzle 29 projects radially and upwardly from portion 28 toward liquid nozzle 23. A passage l3 in boss 21 and portion 28 connects nozzle 29 to air chamber 25 so that air may be forced over nozzle 23 to aspirate liquid, such as perfume,through nozzle member 2 l.

Passage 30 acts as a pump chamber to force air through air chamber 25. A bushing or collar 3| is press fitted in the upper end of bore 30 and has a central aperture 32 through which passes a plunger rod 33. Aperture 32 is slightly larger than rod 33 so that air may pass into chamber 30 around rod 33. Rod '33 has :a decorative operating head 34 on its upper end, shown as resembling a seashell. .Head34 has a projecting lip 35, with an arcuate edge, for a purpose to be described. The inner end of rod 33 is reduced, as at 31, to receive a washer 38, molded from a suitable plasticmaterial, which is flexible enough to be forced over the inner end of rod 33.

A novel feature of the invention is the manner of providing cross-passages between bores I and 2B, and bosses 25 and 33. Referring more particularly to Fig. 8, a closure member or'plate 40 is provided having circular bosses 45, 50, 55 and 60 re pectively of the same diameter and in the same relative locations as passages i5, 23 25 and 3B.

To interconnect the respective bores, a cross cut 4l is milled or otherwise'formed in the material 42 of'casing I-U separating bores l5 and 20. Similarly a cross cut 43 is formed in the material 42 between bores 25 and 3D. Corresponding to these cuts, connectingbosses '45, 41 are formed on plate 40 between circular bosses 45, 5!! and 55, 60, res ectively, but their heights are less than the depths of cuts 4|, 43.

To complete the atomizer, a spring 48 is placed in pump chamber 3!) against washer 38. and plate 40 'is secured to the out r or lower end of easing H). In such securernent, circular bosses 45, 5B, 55 and 6B arealigne'd with bores 5,10, 25, and 30, respectively. As these latter bosses :are less in hei ht than the de th of the cross cuts-small cross-passages are left-connecting bores I5, '20 and 25, 30 respectively.

Spring 48 whose lower end seats on boss'BD normallybiases rod 33 and washer 38 outwardly. To lock'the rod in its inoperative position, head '34 is turned to engage lip 35 beneath head [40f cap I6, with the arcuate edge of the lip seating against the cylindrical surface of cap l6. To operate the atomizer, head 34 is turned to release lip 36, and rod 33 and washer 38 may then be reciprocated to force air through nozzle 29 and across nozzle 23 to aspirate perfume therethrough.

While a specific embodiment of the invention has been shown and described in detail to illustrate the application of the principles thereof, it will be understood that the invention may be otherwise embodied without departing from such principles.
